What really makes it a magnum?

I had an interesting discussion last evening with a friend. He has developed an RL22 load for his 06' using the 168 TSX yielding about 2850 FPS. I shoot the VLD out of my 7mm remmy at about the same, the 160 partition at 3000. The question of the day is, who has the Magnum? His Crown induced contention was: " a 168 going 2800 is a 168 going 2800"

You are faster for your caliber. The 7mm bullets have a higher sd at the same weight, so they will penetrate better(if they are the same construction) and should have a better bc.
If you were both using the same bullet, instead of him using a average bc hunting bullet, and you using a rather high bc hybrid type bullet, it would be closer.
That being siad, it realy doesn't have anything to do with the price of tea in China until the range is extended past a few hundred yards.

But the marketing gurus say you do

Re: What really makes it a magnum?

IMO, You have the magnum, by virtue of the cartridge named '7mm Remington Magnum'.
And while a 30-06, 7-06, or a 284Win, are more or less capable, their case heads don't exceed .473" and/or they don't hold a headspacing belt in their designs.
Of course there are surely contradictions, as internal ballistic standards truly are not.

Re: What really makes it a magnum?

Oh this subject has come up around my campfire a time or two as well. Belts don't count obviously. My 300 Ultra is surely a magnum. The 7 Remington mag is a magnum in name only in my opinion. The lowly old ought six with the heavier bullets will at the very least match,if not surpass the 7 Remmy for velocity in equal barrel lengths. The otter has been proven as a long range target round longer than most can remember. I don't consider it a magnum either. One could say the rounds giving the highest velocity in a given caliber are magnums. That narrows the field considerably. Marketeing execs would hate to loose their ploy of calling a new round a magnum though.

Like tacticool, assault rifle, etc ... it's all a marketing scheme!
